An acquaintance who tries too hard to become one of the "bro's" and constantly refers to himself being in the wolf-pack when he clearly isn't.

It can also refer to that guy who constantly ends sentences with "bro".

Acquaintance: Howz it goin? Bro! Pal! Heard you were at that party last night, decennnt. I was gonna go but I got so drunk with a sh*t-ton of girls and couldn't make it because my car had a flat tire from having too many girls in the backseat. So I stayed home and Fb'ed.
You: Brohard.
Acquaintance: What? Bro. You down to slam a 2'1 of palm bay with the buds!?
You: .......

The kind of lying, cheap, sneaky, smug son-of-a-bitch who claims to be your friend while at the same time will do almost anything in their power to bring you down, then lie like a bitch when they're caught. Claims to be a bro, but is really just a big pussy hiding behind his own socially awkward flaws and insecurities. The kind of kid whom everybody would love nothing more than to push off a cliff and move on with life.

"dude we just cause your room mate jacking 20 bucks from you and his excuse was he was way too stoned to remember what happened"
